<p><tt>qmake</tt>'s fundamental behavior is influenced by variable declarations that define the build process of each project. Some of these declare resources, such as headers and source files, that are common to each platform; others are used to customize the behavior of compilers and linkers on specific platforms.</p>
<p>Platform-specific variables follow the naming pattern of the variables which they extend or modify, but include the name of the relevant platform in their name. For example, <tt>QMAKE_LIBS</tt> can be used to specify a list of libraries that a project needs to link against, and <tt>QMAKE_LIBS_X11</tt> can be used to extend or override this list.</p>

<h2>CONFIG</h2>
<p>The <tt>CONFIG</tt> variable specifies project configuration and compiler options. The values will be recognized internally by <tt>qmake</tt> and have special meaning. They are as follows.</p>
<p>These <tt>CONFIG</tt> values control compilation flags:</p>
<p><table width="95%" align="center" cellpadding="2" cellspacing="1" border="0">
<thead><tr valign="top" class="qt-style"><th>Option</th><th>Description</th></tr></thead>
<tr valign="top" class="odd"><td>release</td><td>The project is to be built in release mode. This is ignored if <tt>debug</tt> is also specified.</td></tr>
<tr valign="top" class="even"><td>debug</td><td>The project is to be built in debug mode.</td></tr>
<tr valign="top" class="odd"><td>debug_and_release</td><td>The project is built in <i>both</i> debug and release modes. This can have some unexpected side effects (see below for more information).</td></tr>
<tr valign="top" class="even"><td>build_all</td><td>If <tt>debug_and_release</tt> is specified, the project is built in both debug and release modes by default.</td></tr>
<tr valign="top" class="odd"><td>ordered</td><td>When using the <tt>subdirs</tt> template, this option specifies that the directories listed should be processed in the order in which they are given.</td></tr>
<tr valign="top" class="even"><td>warn_on</td><td>The compiler should output as many warnings as possible. This is ignored if <tt>warn_off</tt> is specified.</td></tr>
<tr valign="top" class="odd"><td>warn_off</td><td>The compiler should output as few warnings as possible.</td></tr>
</table></p>
<p>Since the <tt>debug</tt> option overrides the <tt>release</tt> option when both are defined in the <tt>CONFIG</tt> variable, it is necessary to use the <tt>debug_and_release</tt> option if you want to allow both debug and release versions of a project to be built. In such a case, the Makefile that <tt>qmake</tt> generates includes a rule that builds both versions, and this can be invoked in the following way:</p>
<pre> make all</pre>
<p>Adding the <tt>build_all</tt> option to the <tt>CONFIG</tt> variable makes this rule the default when building the project, and installation targets will be created for both debug and release builds.</p>
<p>Additionally, adding <tt>debug_and_release</tt> to the <tt>CONFIG</tt> variable will cause both <tt>debug</tt> and <tt>release</tt> to be defined in the contents of <tt>CONFIG</tt> when the project file is processed, causing <a href="qmake-advanced-usage.html#scopes">scopes</a> that test for each value to be processed for <i>both</i> debug and release modes. As a result, it may be useful to define mode-specific variables, such as <a href="#qmake-lflags-release">QMAKE_LFLAGS_RELEASE</a>, instead of general variables, such as <a href="#qmake-lflags">QMAKE_LFLAGS</a>, where possible.</p>
<p>The following options define the application/library type:</p>

</table></p>
<p>The build process for bundles is also influenced by the contents of the <a href="#qmake-bundle-data">QMAKE_BUNDLE_DATA</a> variable.</p>
<p>The <tt>CONFIG</tt> variable will also be checked when resolving scopes. You may assign anything to this variable.</p>
<p>For example:</p>
<pre> CONFIG += qt console newstuff
 ...
 newstuff {
     SOURCES += new.cpp
     HEADERS += new.h
 }</pre>
<a name="defines"></a><a name="defines"></a>
<h2>DEFINES</h2>
<p><tt>qmake</tt> adds the values of this variable as compiler C preprocessor macros (-D option).</p>
<p>For example:</p>
<pre> DEFINES += USE_MY_STUFF QT_DLL</pre>
<a name="def-file"></a><a name="def-file"></a>
<h2>DEF_FILE</h2>
<p><i>This is only used on Windows when using the <tt>app</tt> template</i>.</p>
<p>Specifies a <tt>.def</tt> file to be included in the project.</p>
<a name="dependpath"></a><a name="dependpath"></a>
<h2>DEPENDPATH</h2>
<p>This variable contains the list of all directories to look in to resolve dependencies. This will be used when crawling through <tt>included</tt> files.</p>
<a name="destdir"></a><a name="destdir"></a>
<h2>DESTDIR</h2>
<p>Specifies where to put the <a href="#target">target</a> file.</p>
<p>For example:</p>
<pre> DESTDIR = ../../lib</pre>
<a name="destdir-target"></a><a name="destdir-target"></a>
<h2>DESTDIR_TARGET</h2>
<p>This variable is set internally by <tt>qmake</tt>, which is basically the <tt>DESTDIR</tt> variable with the <tt>TARGET</tt> variable appened at the end. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="dlldestdir"></a><a name="dlldestdir"></a>
<h2>DLLDESTDIR</h2>
<p>Specifies where to copy the <a href="#target">target</a> dll.</p>
<a name="distfiles"></a><a name="distfiles"></a>
<h2>DISTFILES</h2>
<p>This variable contains a list of files to be included in the dist target. This feature is supported by UnixMake specs only.</p>
<p>For example:</p>
<pre> DISTFILES += ../program.txt</pre>
<a name="dsp-template"></a><a name="dsp-template"></a>
<h2>DSP_TEMPLATE</h2>
<p>This variable is set internally by <tt>qmake</tt>, which specifies where the dsp template file for basing generated dsp files is stored. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="forms"></a><a name="forms"></a>
<h2>FORMS</h2>
<p>This variable specifies the .ui files (see <a href="designer-manual.html">Qt Designer</a>) to be processed through <tt>uic</tt> before compiling. All dependencies, headers and source files required to build these .ui files will automatically be added to the project.</p>
<p>For example:</p>
<pre> FORMS = mydialog.ui \
     mywidget.ui \
         myconfig.ui</pre>
<p>If FORMS3 is defined in your project, then this variable must contain forms for uic, and not uic3. If CONFIG contains uic3, and FORMS3 is not defined, the this variable must contain only uic3 type forms.</p>
<a name="forms3"></a><a name="forms3"></a>
<h2>FORMS3</h2>
<p>This variable specifies the old style .ui files to be processed through <tt>uic3</tt> before compiling, when <tt>CONFIG</tt> contains uic3. All dependencies, headers and source files required to build these .ui files will automatically be added to the project.</p>
<p>For example:</p>
<pre> FORMS3 = my_uic3_dialog.ui \
      my_uic3_widget.ui \
          my_uic3_config.ui</pre>
<a name="headers"></a><a name="headers"></a>
<h2>HEADERS</h2>
<p>Defines the header files for the project.</p>
<p><tt>qmake</tt> will generate dependency information (unless <tt>-nodepend</tt> is specified on the <a href="qmake-running.html#commands">command line</a>) for the specified headers. <tt>qmake</tt> will also automatically detect if <tt>moc</tt> is required by the classes in these headers, and add the appropriate dependencies and files to the project for generating and linking the moc files.</p>
<p>For example:</p>
<pre> HEADERS = myclass.h \

<a name="includepath"></a><a name="includepath"></a>
<h2>INCLUDEPATH</h2>
<p>This variable specifies the #include directories which should be searched when compiling the project. Use ';' or a space as the directory separator.</p>
<p>For example:</p>
<pre> INCLUDEPATH = c:/msdev/include d:/stl/include</pre>
<a name="installs"></a><a name="installs"></a>
<h2>INSTALLS</h2>
<p>This variable contains a list of resources that will be installed when <tt>make install</tt> or a similar installation procedure is executed. Each item in the list is typically defined with attributes that provide information about where it will be installed.</p>
<p>For example, the following <tt>target.path</tt> definition describes where the build target will be installed, and the <tt>INSTALLS</tt> assignment adds the build target to the list of existing resources to be installed:</p>
<pre> target.path += $$[QT_INSTALL_PLUGINS]/imageformats
 INSTALLS += target</pre>
<a name="leximpls"></a><a name="leximpls"></a>
<h2>LEXIMPLS</h2>
<p>This variable contains a list of lex implementation files. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="lexobjects"></a><a name="lexobjects"></a>
<h2>LEXOBJECTS</h2>
<p>This variable contains the names of intermediate lex object files.The value of this variable is typically handled by <tt>qmake</tt> and rarely needs to be modified.</p>
<a name="lexsources"></a><a name="lexsources"></a>
<h2>LEXSOURCES</h2>
<p>This variable contains a list of lex source files. All dependencies, headers and source files will automatically be added to the project for building these lex files.</p>
<p>For example:</p>
<pre> LEXSOURCES = lexer.l</pre>
<a name="libs"></a><a name="libs"></a>
<h2>LIBS</h2>
<p>This variable contains a list of libraries to be linked into the project. You can use the Unix <tt>-l</tt> (library) and -L (library path) flags and qmake will do the correct thing with these libraries on Windows (namely this means passing the full path of the library to the linker). The only limitation to this is the library must exist, for qmake to find which directory a <tt>-l</tt> lib lives in.</p>
<p>For example:</p>
<pre> unix:LIBS += -L/usr/local/lib -lmath
 win32:LIBS += c:/mylibs/math.lib</pre>
<p><b>Note:</b> On Windows, specifying libraries with the <tt>-l</tt> option, as in the above example, will cause the library with the highest version number to be used; for example, <tt>libmath2.lib</tt> could potentially be used instead of <tt>libmathlib</tt>. To avoid this ambiguity, we recommend that you explicitly specify the library to be used by including the <tt>.lib</tt> file name suffix.</p>
<p>By default, the list of libraries stored in <tt>LIBS</tt> is reduced to a list of unique names before it is used. To change this behavior, add the <tt>no_lflags_merge</tt> option to the <tt>CONFIG</tt> variable:</p>
<pre> CONFIG += no_lflags_merge</pre>
<a name="literal-hash"></a><a name="literal-hash"></a>
<h2>LITERAL_HASH</h2>
<p>This variable is used whenever a literal hash character (<tt>#</tt>) is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application.</p>
<p>For example:</p>
<pre> # To include a literal hash character, use the $$LITERAL_HASH variable:
 urlPieces = http://doc.trolltech.com/4.0/qtextdocument.html pageCount
 message($$join(urlPieces, $$LITERAL_HASH))</pre>
<p>By using <tt>LITERAL_HASH</tt> in this way, the <tt>#</tt> character can be used to construct a URL for the <tt>message()</tt> function to print to the console.</p>

<p><table align="center" cellpadding="2" cellspacing="1" border="0">
<thead><tr valign="top" class="qt-style"><th>Option</th><th>Features</th></tr></thead>
<tr valign="top" class="odd"><td>core (included by default)</td><td><a href="qtcore.html">QtCore</a> module</td></tr>
<tr valign="top" class="even"><td>gui (included by default)</td><td><a href="qtgui.html">QtGui</a> module</td></tr>
<tr valign="top" class="odd"><td>network</td><td><a href="qtnetwork.html">QtNetwork</a> module</td></tr>
<tr valign="top" class="even"><td>opengl</td><td><a href="qtopengl.html">QtOpenGL</a> module</td></tr>

<tr valign="top" class="even"><td>qt3support</td><td><a href="qt3support.html">Qt3Support</a> module</td></tr>
</table></p>
<p>By default, <tt>QT</tt> contains both <tt>core</tt> and <tt>gui</tt>, ensuring that standard GUI applications can be built without further configuration.</p>
<p>If you want to build a project <i>without</i> the <a href="qtgui.html">QtGui</a> module, you need to exclude the <tt>gui</tt> value with the &quot;-=&quot; operator; the following line will result in a minimal Qt project being built:</p>
<pre>     QT -= gui # Only the core module is used.</pre>
<p>Note that adding the <tt>opengl</tt> option to the <tt>QT</tt> variable automatically causes the equivalent option to be added to the <tt>CONFIG</tt> variable. Therefore, for Qt applications, it is not necessary to add the <tt>opengl</tt> option to both <tt>CONFIG</tt> and <tt>QT</tt>.</p>
<a name="qtplugin"></a>
<h2>QTPLUGIN</h2>
<p>This variable contains a list of names of static plugins that are to be compiled with an application so that they are available as built-in resources.</p>
<a name="rc-file"></a>
<h2>RC_FILE</h2>

<pre>     unix:RCC_DIR = ../myproject/resources
     win32:RCC_DIR = c:/myproject/resources</pre>
<a name="requires"></a><a name="requires"></a>
<h2>REQUIRES</h2>
<p>This is a special variable processed by <tt>qmake</tt>. If the contents of this variable do not appear in CONFIG by the time this variable is assigned, then a minimal Makefile will be generated that states what dependencies (the values assigned to REQUIRES) are missing.</p>
<p>This is mainly used in Qt's build system for building the examples.</p>
<a name="res-file"></a>
<h2>RES_FILE</h2>
<p>This variable contains the name of the resource file for the application. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>

The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="subdirs"></a><a name="subdirs"></a>
<h2>SUBDIRS</h2>
<p>This variable, when used with the <a href="#template"><tt>subdirs</tt> template</a> contains the names of all subdirectories that contain parts of the project that need be built. Each subdirectory must contain its own project file.</p>
<p>For example:</p>
<pre>     SUBDIRS = kernel \
               tools</pre>
<p>It is essential that the project file in each subdirectory has the same name as the subdirectory itself, so that <tt>qmake</tt> can find it. For example, if the subdirectory is called <tt>myapp</tt> then the project file in that directory should be called <tt>myapp.pro</tt>.</p>
<p>If you need to ensure that the subdirectories are built in the order in which they are specified, update the <a href="#config">CONFIG</a> variable to include the <tt>ordered</tt> option:</p>
<pre>     CONFIG += ordered</pre>
<a name="target"></a><a name="target"></a>
<h2>TARGET</h2>
<p>This specifies the name of the target file.</p>
<p>For example:</p>
<pre>     TEMPLATE = app
     TARGET = myapp
     SOURCES = main.cpp</pre>
<p>The project file above would produce an executable named <tt>myapp</tt> on unix and 'myapp.exe' on windows.</p>
<a name="target-ext"></a>
<h2>TARGET_EXT</h2>
<p>This variable specifies the target's extension. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="target-x"></a>
<h2>TARGET_x</h2>
<p>This variable specifies the target's extension with a major version number. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="target-x-y-z"></a>
<h2>TARGET_x.y.z</h2>
<p>This variable specifies the target's extension with version number. The value of this variable is typically handled by <tt>qmake</tt> or <a href="#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="template"></a><a name="template"></a>
<h2>TEMPLATE</h2>
<p>This variable contains the name of the template to use when generating the project. The allowed values are:</p>
<p><table align="center" cellpadding="2" cellspacing="1" border="0">
<thead><tr valign="top" class="qt-style"><th>Option</th><th>Description</th></tr></thead>
<tr valign="top" class="odd"><td>app</td><td>Creates a Makefile for building applications (the default).</td></tr>
<tr valign="top" class="even"><td>lib</td><td>Creates a Makefile for building libraries.</td></tr>
<tr valign="top" class="odd"><td>subdirs</td><td>Creates a Makefile for building targets in subdirectories. The subdirectories are specified using the <a href="#subdirs">SUBDIRS</a> variable.</td></tr>
<tr valign="top" class="even"><td>vcapp</td><td><i>Windows only</i> Creates an application project for Visual Studio. (See <a href="qmake-platform-notes.html#creating-visual-studio-project-files">qmake Platform Notes</a> for more information.)</td></tr>
<tr valign="top" class="odd"><td>vclib</td><td><i>Windows only</i> Creates a library project for Visual Studio. (See <a href="qmake-platform-notes.html#creating-visual-studio-project-files">qmake Platform Notes</a> for more information.)</td></tr>
</table></p>
<p>For example:</p>
<pre>     TEMPLATE = lib
     SOURCES = main.cpp
     TARGET = mylib</pre>
<p>The template can be overridden by specifying a new template type with the <tt>-t</tt> command line option. This overrides the template type <i>after</i> the .pro file has been processed. With .pro files that use the template type to determine how the project is built, it is necessary to declare TEMPLATE on the command line rather than use the <tt>-t</tt> option.</p>
<a name="translations"></a>
<h2>TRANSLATIONS</h2>
<p>This variable contains a list of translation (.ts) files that contain translations of the user interface text into non-native languages.</p>

<a name="ui-dir"></a><a name="ui-dir"></a>
<h2>UI_DIR</h2>
<p>This variable specifies the directory where all intermediate files from uic should be placed. This variable overrides both <a href="#ui-sources-dir">UI_SOURCES_DIR</a> and <a href="#ui-headers-dir">UI_HEADERS_DIR</a>.</p>
<p>For example:</p>
<pre>     unix:UI_DIR = ../myproject/ui
     win32:UI_DIR = c:/myproject/ui</pre>
<a name="ui-headers-dir"></a><a name="ui-headers-dir"></a>
<h2>UI_HEADERS_DIR</h2>
<p>This variable specifies the directory where all declaration files (as generated by uic) should be placed.</p>
<p>For example:</p>
<pre>     unix:UI_HEADERS_DIR = ../myproject/ui/include
     win32:UI_HEADERS_DIR = c:/myproject/ui/include</pre>
<a name="ui-sources-dir"></a><a name="ui-sources-dir"></a>
<h2>UI_SOURCES_DIR</h2>

<a name="ver-pat"></a>
<h2>VER_PAT</h2>
<p>This variable contains the patch version number of the library, if the <tt>lib</tt> <a href="#template">template</a> is specified.</p>
<a name="vpath"></a>

<p>This variable tells <tt>qmake</tt> where to search for files it cannot open. With this you may tell <tt>qmake</tt> where it may look for things like SOURCES, and if it finds an entry in SOURCES that cannot be opened it will look through the entire VPATH list to see if it can find the file on its own.</p>
<p>See also <a href="#dependpath">DEPENDPATH</a>.</p>
<a name="yaccimpls"></a>
<h2>YACCIMPLS</h2>
